Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

Tillage agriculture has led to widespread soil and ecosystem degradation globally. This is especially so in Africa where traditional and modern tillage-based agricultural practices have become unsustainable due to severe disturbance and exploitation of natural resources, with negative impacts on the environment and rural livelihoods. In addition, agriculture in Africa today faces major challenges including increased costs of production and energy, the effects of climate change, and the lack of an effective paradigm for sustainable intensification, especially for small- and medium-size holdings. Africa is facing a serious challenge to food security and as a continent has not advanced towards eradicating hunger. In addition, the population is still growing much faster than on most other continents. This pressure has led to the emergence of no-till conservation agriculture as a serious alternative sustainable agriculture paradigm. In Africa, in recent years, conservation agriculture techniques and methods have spread to many countries, as greater development, education and research effort are directed towards its extension and uptake. This book is aimed at agricultural researchers and scientists, educationalists, and agricultural service providers, institutional leaders and policy makers working in the fields of sustainable agriculture and international development, and also at agroecologists, conservation scientists, and those working on ecosystem services.

This book documents a decade of research, methodological innovation, and lessons learned in an eco-regional research-for-development program operating in the eastern African highlands, the African Highlands Initiative (AHI). It does this through reflections of the protagonists themselves—AHI site teams and partners applying action research to development innovation as a means to enhance the impact of their research. The book summarizes the experiences of farmers, research and development workers and policy and decision-makers who have interacted within an innovation system with the common goal of implementing an integrated approach to natural resource management (NRM) in the humid highlands. This book demonstrates the crucial importance of "approach" in shaping the outcomes of research and development, and distils lessons learned on what works, where and why. It is enriched with examples and case studies from five benchmark sites in Ethiopia, Uganda, Kenya and Tanzania, whose variability provides the reader with an in-depth knowledge of the complexities of integrated NRM in agro-ecosystems that play an important role in the rural economy of the region. It is shown that the struggle to achieve sustainable agricultural development in challenging environments is a complex one, and can only be effectively achieved through combined efforts and commitment of individuals and institutions with complementary roles.

Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.

"Jones beschreibt in seinem Werk die Entwicklung Europas in langfristiger Sicht. Dabei legt er besonderes Gewicht auf die Zeit zwischen 1400 und 1800 und auf Vergleiche mit Asien. Das System, das damals in Europa entstand, ist wichtig für die Geschichte dieses Erdteils und als Vorläufer für die USA, Kanada, Australien, Neuseeland, Lateinamerika und Südafrika." -- Herausgeber.

Welche Konsequenzen wird es haben, wenn in Zukunft die überwiegende Mehrheit der Weltbevölkerung online ist? Wenn Informationstechnologien so allgegenwärtig sind wie Elektrizität? Was bedeutet das für die Politik, die Wirtschaft – und für uns selbst? Diese Fragen beantwortet ein außergewöhnliches Autorenduo: Eric Schmidt, der Mann, der Google zu einem Weltunternehmen gemacht hat, und Jared Cohen, ehemaliger Berater von Hillary Clinton und Condoleezza Rice und jetzt Chef von Googles Denkfabrik. In diesem aufregenden Buch führen sie uns die Chancen und Gefahren jener eng vernetzten Welt vor Augen, die die meisten von uns noch erleben werden. Es ist die sehr konkrete Vision einer Zukunft, die bereits begonnen hat. Und ein engagiertes Plädoyer dafür, sie jetzt zu gestalten – weil Technologie der leitenden Hand des Menschen bedarf, um Positives zu bewirken.
